The debate over gun control continues to be a hot topic in America. Take a look at which states have the strictest and weakest gun laws, according to ratings from the Brady Campaign to Prevent Gun Violence.

Travis Rigas applied for his concealed carry permit and attended a firearms safety course required by law. Shannon Campbell, an instructor with moms4guns.com, said those courses are important.

"You have to qualify on the range," Campbell said. "You have to take a test in the class showing that you're competent with all the bells and whistles of firearms, where the safety's are and how they work."

Even though he completed and passed the firearms safety course, Rigas won't receive his license for another six months. The Warren County Sheriff's Office doesn't have any open appointments.

"We believe in their right to be able to get a permit to be able to carry their firearm legally, we just ask for them to be patient," said Sheriff Larry Sims.

The spike in applications has been caused by the fear that federal gun laws could change.
